Answer:
Option (4) is correct about BQ
Step-by-step explanation:
Given : From the figure : ∠BQA = 54° and ∠BAQ = 36°
Now, Since ∠BAQ = 36° > 30°
So, ∠BAQ is not acute.
⇒ (1) is rejected.
Also, ∠BQA = 54° > 30°
So, ∠BQA is not acute.
⇒ (2) is rejected.
Now, in ΔABQ, By using angle sum property of a triangle
∠BAQ + ∠BQA + ∠ABQ = 180°
⇒ 36° + 54° + ∠ABQ = 180°
⇒ ∠ABQ = 90°
Since, ∠ABQ is right angle so, (3) is rejected.
Now, ∠ABQ = 90° and the line which is exterior to the circle and makes right angle with the radius of the circle is always tangent to the circle.
Hence, Option (4) is correct about BQ.
Therefore, BQ is a tangent line because m∠ABQ = 90°

Answer: 2/3 is the simplest form
<h3>The two possible values for x are x = 60 and x = -9</h3>
===========================================================
Explanation:
Let's assume that x is the largest value of the list. If so then x = 60 because
range = max - min
range = x - 1
range = 60-1
range = 59
Effectively, you work backwards to go from a range of 59 to have x = 60 as the max.
So x = 60 is one possible value. We can't have x any larger or the range would be larger.
But we can have x be smaller. Specifically, it would be the min of the list. If negative x values are allowed, then x = -9 is the other possible x value
Here's why
range = max - min
range = 50 - x
range = 50 - (-9)
range = 50+9
range = 59
Answer:
sin(x) and cos(y) are equal and have ratio of 1 : 1
First find the missing hypotenuse using Pythagoras theorem:
a² + b² = c²
12² + 5² = c²
c = √144+25
c = 13
using sine rule:
using cosine rule:
